Fertilized eggs are the crossroads of development. They represent both the origin and the biological goal of each individual organism. Eggs provide in two ways for the embryo they enclose: They contain developmental instructions given by the mother to direct the initial phases of embryogenesis (see Chapters 11–13), and they are usually provisioned with

Vitellogenesis in two spathebothriidean cestodes
Parasitology Research, 2005Vitellogenesis in two spathebothriidean tapeworms, dixenous adult Cyathocephalus truncatus and monoxenous progenetic Diplocotyle olrikii, has been examined using transmission electron microscopy and cytochemical staining with periodic acid-thiosemicarbazide-silver proteinate for glycogen.

In vertebrates, there are three principal modes of nutrition for developing embryos: (1) the laying down of food stores, synthesized in the liver, in the oocyte (vitellogenesis) (this is the most common mode in nonmammalian species); (2) the direct provision of nutrients to the developing young through the intermediary of the uterine wall by either ...

Vitellogenesis and the Vitellogenin Gene Family
Science, 1981Vitellogenin is synthesized under estrogen control in the liver, extensively modified, transported to the ovary, and there processed to the yolk proteins lipovitellin and phosvitin. In the frog Xenopus laevis there are at least four distinct but related vitellogenin genes.

In the Japanese eel Anguilla japonica, oocyte development has not been observed to occur under ordinary rearing conditions. Therefore, hormonal treatment is necessary to induce ovarian maturation artificially. Weekly injections of aqueous extract of salmon pituitaries were generally conducted for inducing vitellogenesis (Yamauchi and Yamamoto 1982). 17,
